*This battery reconditioning program exceeded my presumptions. It worked on any drill battery, several AA and AAA batteries, **batery.repair** and any camera battery. The steps are simple and the act itself is exciting to do. No matter what type of battery you`ve got, it is sure to function again!*

[@sami59165]

Making use of the kzbin.infoUgkxcJ22tnHH9l1vjdIdEIG27iOG55P7LXI8 reconditioning plan, I just saved 2 auto batteries from being completely junked. The guides were very simple to follow. I wish I would have found this years ago! You may use the guide to recondition any battery type

It's amazing how well this bent wire trick works! Today I found myself trying to manually recharge a phone battery for my gf's mom as she seems to have somehow completely destroyed the charging port (pins are nowhere to be found...). I tried making a little jig with a right angle pinheader and breadboard but I couldn't get good contact. Tried the method shown here, bending wires into small hooks, pushing the battery up to them, then setting something heavy on top (I just used a small portable USB hard drive) and lo and behold it worked perfectly haha! Currently charging happily right now. Thanks for taking the time to post this!

[@stuartlawsonbeattie6200]

I wouldn't knock anyone who minces a usb port, techology is cheap foreign shit, it is easy and westen mugs like us are too stupid to spot it.

[@memoryrinehart]

I bought a universal charger. Two contacts on charger and 3 contacts on battery like yours. What is that middle contact on battery and can I possibly have it in reversed??

[@memoryrinehart]

She had same problem as me with port. They loosen up as you hold them while charging, then eventually drain battery instead of charging it. So frustrating... Btw fyi on gospel: Acts 2:38 Acts 22:16 Mark 16:16

[@paulfreedel4709]

Always obvious after we see. THANKS EcProjects. If you don't have a Power Station, PSU, you can use a 'AAA to AA converter', solder wires onto that, taping the wires onto the table and connect the battery. Put the 'AAA to AA converter' into a Li-Ion battery charger.

[@ObsequiousV4]

If you have any microchip controllers with the little spare sets of pin clip arrays, you can crack a few off and use them to line up with the pins since they're pretty rigid.

[@aerotro]

I recently made a little Polystyrene cradle to charge my daughters phone battery when she forgot her charger and left it at home, it was quite stable to as the polystyrene was none slip, made 2 small loops of wire hooked into the polystyrene foam opposite the terminals and it was portable too ;)

[@haydenc2742]

CC/CV charge pattern, always good to not push too much current in too fast, good video!

[@Phjghh]

Excellent idea about that taping method. I hated to hold wire on the battery and staying like that for minutes!

[@SuperEvanbaxter]

Awesome trick. But you can easily do this without a variable DC bench power supply. Just take a USB data cable, cut the end which connects to your phone and strip some insulation at that end. Then connect the cable with a USB port/ wall charger that gives 5V DC output, connect the battery's positive terminal with the red wire of the data cable and negative terminal with the black one as shown in the video and you're done. I've revived some of my apparently dead Lithium batteries this way.

[@biggadfly]

This is how you can easily burn down a house or apartment building. Someone will connect the full power instead of data cable and that is the end of things. It would be a very easy mistake to make. Also some data lines put out only 1.2 volts.

[@mamteshduhoon3439]

very outstanding

[@mamteshduhoon3439]

nice

[@TheActualTed]

@@biggadfly What is a "full power"? Except the data transfer lines usb has +5V and GND. The 5V should do the job without problems, unless you overvoltage it - that's where watching over the charging process with multimeter or getting a charger circuit like TP4056 gets quite important.

[@memoryrinehart]

I bought a universal charger. 2 contacts on charger and 3 on battery like yours. What is that middle contact on battery for and can I possibly have battery in reversed??

[@WaltonPete]

Very handy tip which could be used for a variety of batteries and for powering items directly from a bench PSU although you have to be careful not to overcharge Li-on batteries as this is a potential fire hazard!

[@EcProjects]

+Pete Allum Thanks for your comment. Yeah, it's very important to get the voltage limit correct. Especially with higher currents it doesn't take long for things to go wrong!

[@TheDIMONART]

you can use a little neodymium magnets for better and strong contact between Li-ion baterry and crocodiles))

[@rpbajb]

This will work with a power bank also if you don't have a bench supply. I charged a battery that my old phone could not charge. The battery contained a protection circuit and refused further charge at 3.90 volts, so it's quite safe.

[@themysterygamerpl7089]

Every of them has BMS (protection) because every phone would be dead if they wouldnt have it

[@rpbajb]

@@themysterygamerpl7089 Not so. Many cells are bare, and the protection circuit is on the associated PCB.

[@jjjjjj428]

How do you charge cell phone batteries with wire connectors already attached to battery like samsung galaxy phones

[@alexrivet1732]

Small wire inside the connector or splice

[@MrFernandoBedoya]

Excellent video. What kind of tool do you use here, an oscilloscope?

[@emhean]

Mads Nielsen? like the boy who disappeard in the Netflix tv-series Dark

[@arrowstheorem1881]

Simple yet it works! What are these types of batteries called? these rectangular flat cells. look like lipo packaging but its lithium ion

[@sonighanender6774]

Can I use battery of one mobile in second mobile by connecting the mobile charging pins to battery pins through wire as socket of battery is not same. Will it work.

[@angeleocorrodead]

If it's compatible, then yes.

[@krunoslavhrastic605]

I thought you died.... and after like a month you are back.. xD

[@redwanhasan1721]

Increase the voltage beyond 4.2-4.3 V and you got yourself a potential bomb. So I wouldn't recommend doing this rather buy a li ion charger circuit which are very cheap.

[@blackz06]

100% safe with a supply that does CC and CV.

[@christincrawford1614]

That song at the beginning and end is epic. Where is it from ??

[@memoryrinehart]

Its available from youtube music. I did a vid using it called "Adept story" if you care to watch. Fyi Acts 2:38 Acts 22:16 Mark 16:16 gospel

[@koulouri9180]

Can an old wall adapter work? By cutting the micro usb and exposing the wires

[@atadabwani8019]

how to fix small battery in phone

[@AbuMona81]

You need to put diod on Red wire.

[@edism]

Nope.

[@BlazeGelos]

Yes, you have to prevent current flowing into your power supply to avoid damage.

[@sorrychangedmyusername3594]

So much bots on your channel but it is not as malicious huh.

[@jakejones5736]

I don't get it. For a given load, how can you set both voltage AND current?

[@EcProjects]

You can't :) It's just a limit -- maximum 4.2v and maximum 500 mA for example :)

[@jakejones5736]

Immediately after I posted, I thought that maybe you were referring to limits. I even considered editing my comment. Thanks for the clarification.

[@mamteshduhoon3439]

very nice

[@sanjaykumarpathak2317]

Is it correct or not anser me

[@tombaenadaglio5425]

NICE

[@Viper-113]

[@stuartlawsonbeattie6200]

Take the battery out.

[@arrowstheorem1881]

I always wanted to know what type of lithium ion battery is this configuration or 3 pin flat rectangular cells called? seems like its evolved from Nokia batteries

[@grahamjones6712]

I think they actually originated from camcorder batteries before mobile phones

[@prathmeshmanohargavit6384]

Nice

[@imherohessan8443]

thanks man.

[@Deses]

This is the ghettoest way to charge a battery. I hope these batteries have protection or you'll have a nice firework show on your workbench!

[@eclipsesolar8345]

Obviously that everyone as that machine at home . Obviously 😤🤦🤦🤦🤦🤦

[@rowdykjjj79]

I think its great but one thing should probley put tape between the two wire were they connect to battery or just stand up a small piece of no conductive material small plastic or rubber duck tape. Or eltric tape as so if the wires do come. Free you don't short across or in case both come free they don't touch an that be Ni good an Jake the standard,for cell bat is,0.5 an 3.7 v nomnail is. What most say. They are, 4.2. Is what. They realy are, standard so he set amp an volts, don't forget this is dc were messing with amp times volts give watts think that's right if not its volts times amp gives watts,

[@mohitpandurangwaghade5]
